Hapiru Island is a full working dungeon world with Custom Items, Mob drops, and Bosses.
I used Curacao Island by CountVeggie and Floating Islands by Nefashu as the base.
Then i began work adding in a storyLine, NPCs, and Tons of redstone work.
Since the mechanics of this dungeon require Bukkit plug-ins to function i have
to host it on my server. but this helps cause anyone can come and play through it.

Go to CrookedCraft.com For details on joining and Playing.
Bring a friend and go through the adventure together

Full Quest line
Custom items (Parts to the Broken door to the Temples)
NPCs
Puzzles
Hidden Loot
Mob Bosses
and more....

I will release the World file and all plug-ins used to make it function when its 100% done

To play it solo you will have to run your own local bukkit server. Most of the dungeon mechanics like redstone mob spawning, And custom keys for doors. I guess i could remake it in Adventure Craft and release it that way when i'm done. All i know is i can't release it just vanilla map. or its un-playable
